Electronic shelf labels for pet stores

A pet shop sells food in bags of several sizes, accessories in very mixed formats and, sometimes, live animals and aquatics. Electronic shelf labels fit best on pet food, where the bag price and the price per kilo must stay in step, and on brand promotions. Wet areas and live animals are where the evidence is thinnest.

What makes this store different

A pet store is neither a small supermarket nor a hardware shop. It combines three businesses with different demands: fast-turning, thin-margin food, a long tail of accessories with many lines and slow sales, and, where there is one, a livestock area with its own rules.

The money is in the food. In Germany, where the trade bodies publish a detailed breakdown, their figures put the whole pet industry at just under 7 billion euros in 2025. Prepared pet food stayed almost flat at about 4.3 billion euros, while supplies and accessories fell 4.6 % to just under 1.1 billion (ZZF/IVH). No equivalent figure for UK pet shops that we could verify was found, so this page does not give one. The pattern is still useful: the food shelf carries the shop.

That explains why labels matter unevenly here. The food bay has few brands but each in many pack sizes, and it is where a pricing error hurts most because the customer has a phone in hand.

Dry food: one product, four unit prices

A dog food can hang on the shelf in 3, 7, 12 and 15 kg bags. Nobody takes the 15 kg bag without working out whether it is cheaper per kilo than the 3 kg one, and the rules are built around that. Under the Price Marking Order 2004, price indications must be unambiguous, easily identifiable and clearly legible, located near the product so the customer can find them without asking staff. Where a unit price appears next to a price for a non-metric quantity, the unit price must be the more prominent of the two (legislation.gov.uk). The detail of which products need a unit price sits elsewhere in the Order and is not reproduced here; check it for your pack sizes.

On paper the usual failure is updating: the 15 kg bag goes up and nobody reprints the unit price ticket, or one is changed and not the other. In an electronic system the unit price is not typed, it is calculated. So what to check when evaluating a rollout is not the screen but where the net weight of each pack comes from and who maintains it. If the product record holds the wrong weight, the label will show a wrong price per kilo with perfect clarity.

There is a trade-specific wrinkle: pet food brands change recipes, packs and fill weights often, and a 12 kg bag quietly becomes an 11.5 kg one without anyone in store noticing. If net weight is a hand-edited field, that change is a bigger source of error than the price itself.

Large bags also create a physical problem. They stack on the floor or on low pallets, and the label sits on an edge or rail at floor level, where it gets kicked and dirty. Placement, screen size and mounting count for more than the particular model; the LCD versus e-paper comparison covers what changes with the technology.

Brand promotions and reference prices

Pet food runs on campaigns: “buy two and save”, gifts with purchase, launch packs. Many are funded by the brand and come with short dates. Two concrete issues.

First, price reductions. Article 9 of the Price Marking Order lets a trader signal a reduction with a general notice, provided the details of the reduction are prominently displayed, unambiguous, easily identifiable and clearly legible. The text of that article sets no look-back period (legislation.gov.uk). The EU rule is stricter: Directive 2019/2161 (Omnibus) requires an announced reduction to cite the lowest price applied in the previous 30 days (EUR-Lex), and it matters if you sell into EU member states. Other UK rules on misleading price claims also apply and are outside this page. How the reference price works is covered in the page on was/now pricing and reference prices. A system that changes prices weekly should keep a price history either way, because that is how you prove a claim.

Second, promotions like “second bag half price” are not a shelf price but a till rule. If the label shows one price and the till applies another logic, there is a mismatch even if both figures are right. The gap between shelf and till has its own analysis in the page on dynamic pricing.

Aquatics, reptiles and wet areas

This is the part with the least public evidence. No independent proof was found of electronic labels running for a sustained period in aquatics areas. Manufacturers mention water and dust resistance in their material, and one highlights pet-store use (Vusion), but that is marketing information.

What can be said with rigour is what to ask:

• What protection the datasheet declares (IP rating) and against what: dust, splashes and immersion are different things.
• How the label behaves with condensation, which forms on cold glass and near heated tanks.
• What happens to the radio near large bodies of water and metal shelving, which affect gateway coverage.
• Whether routine cleaning (disinfectant, a wipe-down) damages the holder or the display.

The sensible approach is to trial a small number of labels in that area for a few weeks before committing the rest. For live animals, the price usually appears on the tank or the animal’s card, and selling them is subject to welfare rules with extra information duties that have nothing to do with the price label.

Competing with the online price

The pet food customer compares with the online shop, often with a subscription and regular delivery. A physical store cannot always match the price, but it can avoid a gap caused by carelessness: the website price changing on Monday and the shop price on Thursday.

Electronic labels shrink that gap only if web and shop prices come from the same source. That is an integration question with the back-office system, not a hardware one. If the shop keeps two price lists, the problem stays just as open with digital labels. Before buying, find out whether pricing policy is one price or one per channel, and who decides.

A public reference: Kölle Zoo

The clearest example found is the Kölle Zoo chain, with 28 stores in Germany, Austria and Belgium, which was fitted with about 300,000 Solum labels in eight weeks according to a July 2026 report. The company justifies the project by central management of prices and promotions and by freeing staff time to serve customers (invidis). The report mentions neither aquatics nor live animals and gives no savings figures, so it shows that a pet chain does this at scale, not what the return is.

No comparable public rollout by a UK pet retailer was found.

What it costs and when it pays back

Cost per label does not depend on the sector. What changes is the distribution: a pet store of 300 to 600 m² has fewer lines per square metre than a supermarket, and many of them move slowly. The business case is therefore usually not saved relabelling hours but fewer unit-price errors and the speed to follow campaigns. That is a working hypothesis, not a figure measured in the sector.

To test it with your own numbers, the TCO calculator lets you run scenarios, and the pricing overview explains how cost splits between investment and instalments.

How to start

1. Start with food and branded treats, where unit prices and campaigns concentrate the errors.
2. Audit net weights in the item master before installing anything.
3. Trial the wet area with a small batch, or leave it out of phase one.
4. Unify the price source between shop and web before deciding whether the project pays.
5. Leave live animals out, with their own signage.

Limits of this page

The evidence base for this sector is smaller than for supermarkets or DIY: one public chain reference, outside the UK, and almost all material on aquatics comes from manufacturers. No savings figures are quoted because no independent measurements were found.
